Effect of resource conservation technologies (RCT’s) on yield and water productivity of wheat (Triticum aertivum L.) under vertisols of Tungabhadra project command area of Karnataka
The resource conservation technologies (RCT) such as precision land leveling, zerotillage (ZT) and bed planting have been shown to be beneficial in terms of improving soil health, water use, crop productivity and farmers’ income (Gupta and Seth 2007)
Many studies were conducted on RCTs based single crop in rice-wheat system but no attempt has been made to studythe effect of combined RCTs in wheat in Tungabhadra project (TBP) command areas, this study was proposed
Summary
Effect of resource conservation technologies (RCT’s) on yield and water productivity of wheat (Triticum aertivum L.) under vertisols of Tungabhadra project command area of Karnataka. Laser-assisted precision land leveling considered as a precursor technology for RCTs have been reported to improve crop yield and input-use efficiencyincluding water and nutrients (Jat et al, 2006) This results in saving of excessive loss of irrigation water through deep percolation and increases the application efficiency up to 25 per cent (Sattar et al, 2003). To make system economically viable, it is essential to reduce the cost of input per unit Under such situation, zero tillage in laser leveled land technology could be a valid option to reduce the turn around time, cost and establishment of good plant stand of wheat without loss in productivity and sustainability of natural resources with increase in water production efficiency. The experiment consisted of eight treatments viz., T1 : Control (Farmer’s practice i.e. normal leveled with bullock sowing)
